Post Office workers and managers will stage a fresh strike on Saturday over a dispute about jobs, pensions and closures.

Members of the Communication Workers Union (CWU) and Unite will mount picket lines across the country on one of the busiest days of the year.

The unions are embroiled in a long-running row over the franchising of Crown Post Offices - larger branches usually located on high streets - in addition to job-losses and the closure of a final salary pension scheme.

Dave Ward, General Secretary of the CWU, said: "The Post Office is now at crisis point. It needs a new strategy as a matter of urgency."

Unite union officer Brian Scott added: "We believe that Saturday is the day when most people will be dispatching their cards and parcels to their relatives and friends abroad.
